Figure 10 iliustrates a slightly modified construction. This improvedreproducing sheet consists briefly of a master sheet I, a carbon sheet 2and an antismudge sheet 3. These sheets or sections I, 2 and 3 may beformed from a single sheet of paper which is creased to'set oil thesheets or sections oil! from the remainder of the.scorIngIothatthisportionI or the anti-smudge sheet may be severed alongposedincoveringanri removed from original condition so that theanti-smudge sheet shielding relation to the coated surface of the carbonsheet while the remaining .portion of the anti-smudge sheet is disposedback of the carbon sheet and the exposed portion of the coated face ofthe carbon sheet engaged the rear face of the master sheet. while therehas been shown one portion 3' it is to be understood that additionalportions of this nature may be provided by properlyv scorin theanti-smudge sheet.

The duplicator as manufactured and supplied to the user is folded asshown in Figures 2 and 3 to dispose the master sheet anti-smudge sheetbetween the master sheet and the coated surface of the carbon sheet.Since the coated surface of the carbon sheet is disposed inwardly, thecarbon will not be rubbed off or soil at the front and the theanti-smudge sheet with its rear face presented rearwardly and since thisface of the masterrsheet bears the reproduction of the subother sheetsof a stack of duplicators. when the duplicator is used the operatorgrasps the carbon sheet by the uncoated edge portion 2 thereof and turnsit to the position shown in Figures 4 and 5. In this position the carbonsheet is disposed between the anti-smudge sheet with its coated surfaceconfronting the master thereof. 2' of carbon sheet to be understood-thatthe carbon sheet may be ofsuch width that its uncoated edge portion maybe left flat as shown in Figure 10. with the duplicator so folded it mayhe placed in a typewriter or other suitable machine and data typedthereon, or subject matter may face of the master sheet with a pen orpencil. As subject matter is typed or otherwise inscribed upon the frontface of the mastersheet a reproduction of the same in reverse will beproduced upon the rear face of the master sheet by action Whilethe-uncoated'side edge p rtion of the carbon sheet and since thereproductions on the rear face of the master sheet are directly backofthe originals on its frontface they will occupy the same positions inthe form marked in reverse uponthe rear face that they do in the formupon the front face. 1

After the subject upon the front face of the master sheet, it is thetypewriter will be disposed between the carbon sheet and the rear faceof th master sheet and prevent smudglng of the rear face of the mastersheet. Figure shows master sheet and an anti-smudge sheet cut to form arecess I through which the lower end of be inscribed upon the front"iect matter in carbon and a sheet of P p r to receive thc copy isdisposed against this face of the master sheet; pressure of theduplicating machine as the duplicator and the sheet of paper are sheetand the master' sheet and bearing against the rear face 2 has been shownfolded, it is adjoining corner portionsof the portion 2' is exposed.This permits the carbon sheettobe readily grasped by its lower freecorner and the sheets easily turned from one posl-- tion of assembly toanother.

and since' the anti-smudge treated to prevent carbon from reproductionsof subiect matter of the master sheet in front of the anti-smudgev sheetwill a face oftnis portion-of-the anti-smudge sheet. It will thus beseen that both'facea of the anti-smudge 'sheetwill at all timesbe' freefrom carbon and cannot cause the master sheet or other sheets tobesmudged or "otherwise M disfigured by carbonadheri g'to it. In order tomake a reproduction of sheet "is chem callyupon the portion.

An exact copy of the subject mattertyped or otherwise inscribed upon the master sheet will thus bereproduced upon paper. Numerous copies may. thus be produced byrepeatedly passing the duplic tor and a sheet of paper through'aduplicating machine. After a sufllcient number of copies have been made,the master sheet is refolded to its initialposition and the duplicatormay b put away for future use.

From the foregoing description, the construction and operation of myduplicating form will be readily understood and it will be seen that Ihave provided a comparatively simple, efficient means for carrying outjects of the invention. I
